About this trial

This is an interventional treatment trial for Barrett's Esophagus focused on measuring Barrett's Esophagus, Nexium

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • A biopsy-proven diagnosis of Barrett's esophagus segment length greater than 2cm with no dysplasia or adenocarcinoma.
  • Clinically normal laboratory results and physical findings at screening.

Exclusion Criteria:

  • A history of esophageal, gastric or duodenal surgery, including antireflux surgery or endoscopic antireflux procedures, except for simple closure of an ulcer.
  • Evidence of the following diseases or conditions:
  • Barrett's esophagus less than or greater than 2cm that is positive for high grade dysplasia or adenocarcinoma
  • Signs and symptoms of gastric outlet obstruction
  • Active peptic ulcer disease
  • severe liver disease
  • Pancreatitis
  • Malabsorption
  • Active inflammatory bowel disease
  • Severe pulmonary, cardiovascular or renal disease
  • Impaired renal function or abnormal urine sediment on repeated examinations
  • esophageal stricture or active, severe esophagitis.

    Outcomes

    Primary Outcome Measures

    Measure PGE production in Barrett's metastatic tissue & determine the reduction from baseline of PGE production would be equivalent on Day 10 in esomeprazole 40mg bid + aspirin treatment compared to esomeprazole 40 mg bid + rofecoxib 25 mg qd treatment

    Secondary Outcome Measures

    To determine in which of the four treatment groups the reduction in the baseline in PGE2 production, COX-2 enzyme activity and PCNA expression in Barrett's metaplastic tissue is the greatest.

    5. Study Description

    Brief Summary
    This study evaluates PGE2 production, COX-2 enzyme activity and PCNA expression in Barrett's metaplastic tissue. All patients will have a baseline endoscopy with multiple biopsies. The patients will then be receive four dosing regimens (esomeprazole, esomeprazole and aspirin, esomeprazole and rofecoxib, or rofecoxib alone) consecutively each for a 10 day dosing period, whilst undergoing further follow up endoscopies and multiple biopsies.
